Children less fit than their parents were, study finds

NOT SO ACTIVE:Studies on the running fitness of 25 million children have shown a performance decline since 1975 and that 80 percent of youth globally are sedentary


Today’s children cannot keep up with their parents. An analysis of studies on millions of children around the world found they do not run as fast or as far as their parents did when they were young.

On average, it takes children 90 seconds longer to run a mile (1.6km) than their counterparts did 30 years ago. Heart-related fitness has declined 5 percent per decade since 1975 for children ages nine to 17.

The American Heart Association, whose conference featured the research on Tuesday, says it is the first to show that children’s fitness has declined worldwide over the past three decades.

“It makes sense. We have kids that are less active than before,” said Stephen Daniels, a University of Colorado pediatrician and spokesman for the association.

WHO numbers suggest that 80 percent of young people globally may not be getting enough exercise.

Health experts recommend that children aged six and older get 60 minutes of moderately vigorous activity accumulated over a day. Only one-third of US kids do now.

“Many schools, for economic reasons, don’t have any physical education at all,” Daniels said.

Sam Kass, a White House chef and head of US first lady Michelle Obama’s Let’s Move program, told the conference on Monday: “We are currently facing the most sedentary generation of children in our history.”

The new study was led by Grant Tomkinson, an exercise physiologist at the University of South Australia. Researchers analyzed 50 studies on running fitness — a key measure of cardiovascular health and endurance — involving 25 million children aged nine to 17 in 28 countries from 1964 to 2010.

The studies measured how far children could run in between five and 15 minutes and how quickly they ran a certain distance, ranging from half a mile to two miles. Today’s children are about 15 percent less fit than their parents were, researchers concluded.

“The changes are very similar for boys and girls, and also for various ages,” but differed by geographic region, Tomkinson said.

The decline in fitness seems to be leveling off in Europe, Australia and New Zealand, and perhaps in the past few years in North America.

However, it continues to fall in China, but Japan never had much falloff — fitness has remained fairly consistent there. About 20 million of the 25 million children in the studies were from Asia.

In China, annual fitness test data show the country’s students have been getting slower and fatter over the past couple of decades.

Experts and educators blame an obsession with academic testing scores for China’s competitive college admissions, as well as a proliferation of indoor entertainment options like gaming and Web surfing for the decline.

Chinese Ministry of Education data show that in 2010, male college students ran 1,000m 14 to 15 seconds slower on average than male students a decade earlier. Female students slowed by about 12 seconds in running 800m.

Motoaki Nito of the Sports and Youth Bureau at the Japanese Ministry of Education, Culture, Sports, Science and Technology said there had been a decline in physical fitness among youth since the 1980s.

To turn that around, the government has urged municipalities and schools to promote youth fitness. Nito said that this had resulted in a gradual increase of physical strength, which while not equal to levels seen in the 1980s, had reversed the trend.
